ImpulseRC Mr Steele Alien PDB *V2*

Mr Steele teamed up with the guys at ImpulseRC and Flyduino to develop a new PDB for the Alien. Steele knew what features he wanted - a PDB with a built in OSD and microphone - but it would have to simplify the build instead of making it more complex.

The final result is nothing but exceptional. The PDB is made specifically to connect to the KISS FC with the provided cables - it just plugs right in. The ESC power and signal leads can be soldered to the PDB very cleanly with short lengths of wire, and the camera and VTx have their own dedicated solder pads with filtered voltage outputs with cascading regulators for higher efficiency and clean power output. Only the receiver needs to be soldered to the KISS FC. This simplifies building an Alien with KISS electronics a lot!

Steele likes to fly with a microphone on the quad. This allows him to hear the sound coming from the motors on his quad, which in turn lets him to detect any issues (like a failing or obstructed motor) just by hearing the change in the sound. However, not any microphone will work well. Most microphones that come with FPV systems suffer from severe audio clipping due to the loud wind noise, but the microphone on the Mr Steele PDB is a high quality electret microphone with Automatic Gain Control (AGC) technology. AGC dynamically adjusts the gain depending on the volume, so when you put the quad on the ground you can hear faint sounds like footsteps and voices, but when you are flying and doing full throttle punch outs the gain adjusts so that the audio doesn't clip horribly!

The OSD displays voltage, current and mAh consumed at the top of the screen. You can also adjust PID's, Rates, and other flight controller settings through the OSD, just with the sticks!
